Definitions

  • the invention relates to a water filter, in particular a pond filter, according to the preamble of claim 1.
  • a water filter in particular a pond filter
  • Such a filter is for example from the DE 102 40 454 A1 known. It comprises a filter screen, usually designed as a prefilter, on the upper side of which the pond water to be purified is passed through a water supply, which then drips through the filter screen and, if necessary, passed through a drain after passing through a fine filter back into the pond or to a subsequent filter unit becomes.
  • the invention is therefore based on the object here to bring about an improvement and to create a filter with less maintenance. This object is achieved by a filter with the features of claim 1.
  • the cleaning device according to the invention is already part of the filter and arranged so that between it and the filter screen, a relative movement is feasible. As a result, the cleaning device moves along the surface of the filter screen along or vice versa, whereby dirt particles are removed without the filter screen must be removed from the filter.
  • the cleaning process can for example be initiated manually by an outstanding from the housing of the filter actuator. However, it is particularly advantageous if the cleaning process takes place via a motor drive. As a result, the cleaning of the filter screen can be automated, especially if a control of the engine is provided, which puts this in regular or demand-matched intervals for the cleaning operation in operation.
  • the cleaning device which may comprise, for example, a scraper or scraping brush and a subsequent brush strip for thorough cleaning of the screen holes, can be moved over the screen surface at certain intervals in the manner of a windshield wiper. To protect the Schmutzabstreifers this can be lifted in the backward movement of the filter. An even more thorough cleaning can be achieved if two cleaning brushes are provided, one of which is the Cleans the top of the filter and one the bottom of the filter screen, as well as on the bottom dirt in the form of mud and algae occurs.
  • the cleaning brushes can be arranged opposite one another, wherein only one brush would have to be driven and the other, for example, can be moved by a permanent magnet with the first brush. A linear movement of the brushes can be initiated for example via a spindle. However, the brushes can also be moved in opposite directions, for example on rotating toothed belts.
  • a filter according to the invention are possible in which the filter screen is fixed and the cleaning device is moved in contrast.
  • cleaning device and filter screen can be designed to be movable and in particular to perform counter-rotating movements.
  • the filter screen is arranged to be movable relative to the rigid cleaning device.
  • the filter is shown with a housing 1, the front wall is shown broken out for reasons of clarity.
  • the housing 1 is completed on the top by a cover, also not shown, with which the filter can be closed.
  • the filter has a water supply 2, which is fed from two feed rates 3 with water to be filtered.
  • the water supply 2 has a slot nozzle 4 with an inner tongue over which the slot width is adjustable.
  • the filter screen 5 has holes, not shown, with a filter fineness of preferably 0.1 mm to 0.5 mm, through which the water is freed of large impurities, by-dripping through.
  • the filter screen 5 is in the illustrated embodiment, a partially flexible filter belt, preferably made of stainless steel or plastic, which is not stretchable but rollable. It is preferably formed from a filter fabric whose ends are connected to each other, for example, by welding, gluing or sewing, so that as shown results in a circulating endless belt in the manner of a conveyor belt.
  • water to be filtered is applied via the slot nozzle 4 to the region 15 of the top side of the filter screen 5 which is schematically outlined in FIG.
  • the size of this area can be varied by the adjustable slot width of the slot nozzle 4, the pressure of the supplied pond water and the angle of attack of the filter screen 5.
  • a dirt wall 9 builds up on the filter screen 5.
  • the other areas of the filter screen 5 dirty.
  • the filter therefore has a cleaning device, which is formed in the illustrated embodiment by a dirt wiper 11, a cleaning brush 12 for cleaning the top of the filter screen 5 and a cleaning brush 13 for cleaning the bottom or inside of the filter screen 5 ( see Fig. 2).
  • the filter screen 5 which is guided over two tensioning and drive rollers 14, is moved in the direction of the arrow 16. At the top of the filter screen 5 adhering dirt is thereby detected by the wiper 11 and falls into an extending into this area collecting container 17.
  • the collecting container 17 has a handle 18 and can thus be taken out occasionally to remove the collected dirt particles. It is also possible to clean the collecting container 17 by this is flooded by a water supply, not shown, after which the dirt particles are led out together with the flooding water through a dirt drain 19.
  • the first cleaning brush 12 is behind the dirt wiper 11, so that first the coarse dirt is stripped and not stuck in the cleaning brush 12, 13.
  • the illustrated embodiment of the filter has an automatic drive by means of a motor 20. This can circulate continuously for cleaning the filter screen 5. However, since the contamination of the filter screen 5 progresses rather slowly, this will normally not be necessary. It is therefore sufficient if the engine 20 is operated intermittently.
  • a controller could detect the degree of contamination of the filter screen 5 by means of a sensor and then turn on the motor 20 at intervals. However, such a sensor is often expensive and prone to failure, so that an embodiment is recommended in which the motor 20 is set at regular intervals in operation and stopped again.
  • the motor 20 preferably does not run in one direction only, but also in a different time unit in the opposite direction. For example, the cleaning device is operated so that the motor 20 is operated starting from the illustration in Fig. 3 approximately every 30 minutes 30 seconds clockwise, then 15 seconds in reverse and then rest again for 30 minutes.
  • the entire prefilter shown in Fig. 3 (without the water supply 2) about a pivot axis 21 in the direction of arrow 22 can be folded upwards, so that the underlying elements of the filter are freely accessible ,
  • the filter according to the invention is characterized by extremely high ease of use, since the collecting container 17 must be emptied only at very long intervals.
  • the filter therefore allows for long periods of virtually maintenance-free filtering of ponds or similar waters.
